The effect of crystallographic orientation on the micromechanical deformation and failure behaviors of DP980 steel during uniaxial tension

► The individual crystallographic orientations of the constituent phases in DP980 were identified. ► A technique of direct mapping of filtered microstructure into finite element meshes was used. ► CPFEM revealed the effect of crystallographic orientation on the micromechanical behaviors of DP980. ► CPFEM captures the heterogeneity of strain-stress partitioning. ► CPFEM explains the effect of microstructure heterogeneity on the hot spots for void formation.
